Mathematics

Answer:

x=-12

Step-by-step explanation:

x^2-24x+144=0

When you see it as =0, that doesn't mean it's 0. it means it needs more deep solving.

x^2+24x+144-144=0-144

x^2+24x=-144

x^2+24x+12^2=-144+12^2

x^2+24x+12^2=0

(x+12)^2=0

x+12=0

x=-12

Answer:

x = 12

Step-by-step explanation:

Step 1: Write quadratic

x² - 24x + 144 = 0

Step 2: Factor

(x - 12)(x - 12) = 0

Step 3: Find roots

x - 12 = 0

x = 12

So this has to do with permutations and honestly I need an explanation on how I can figure these out.
AnnZ [28]
Well, the answer quite simple ....there are 4! ways to arrange these numbers...and as 4! = 4*3*2*1 = 24

hence 24 is the correct answer....


u can also remember it by theorem of multiplication as.....in first place (I.e. first code can be any no. out of 4,5,2&7 ....so 4*.....

as first place is acquired by a certain no. that leaves three no. to fill third place and when third place I'd occupied it leaves 2 numbers to fill second place and lastly only one no. to fill the last place .....so it's result will be like 4*3*2*1.



I know this is pretty much confusing ....but still I tried my best....

if anything troubles u here feel free to ask me
